There is quite a good Irish Archaeological Facebook community but it is very hard to keep up with it all ... especially on those days when life gets in the way.
I came across the young artist/illustrator, JG Odonoghue, on Facebook who, like Jane Tomlinson, has some of his illustrations turned into cards - all with in depth information about the site (mostly around Cork and Kerry).
An example of his work here...
